    Abstract: A keycap assembly can include a keycap that includes a chargeable light emissive material. The keycap assembly can include a light sensor configured to sense light emitted by or incident to the chargeable light emissive material. The keycap assembly can further include a microcontroller. In certain implementations, the microcontroller includes a processor and a memory device storing instructions that, when executed by the processor, cause the microcontroller to: receive an electrical signal from the light sensor; and determine a property of the chargeable light emissive material based on the electrical signal, where the property includes at least one of a charge level or an illumination intensity.

    Abstract: An input device for an electronic device includes an enclosure and a top member defining an input surface having multiple differentiated input regions. The input device further includes a first force sensing system associated with a first area of the top member and including a first group of the differentiated input regions, and a second force sensing system associated with a second area of the top member and including a second group of the differentiated input regions. The input device further includes a touch sensing system configured to determine which input region from the first group of the differentiated input regions corresponds to the first force input and to determine which input region from the second group of the differentiated input regions corresponds to the second force input.

    Abstract: Systems and methods for decoupling the electrical and mechanical functionality of a depressible key are disclosed. The depressible key can include a non-contact proximity sensor, such as an optical sensor, to detect motion of the keycap. The output from the optical sensor is used to determine a distance, velocity, acceleration, and a force applied during a keypress.
